Brown carbon (BrC) has been recognized as an important contributor to global warming due
to its absorption of solar radiation with strong wavelength dependence. While early studies …

Secondary organic aerosol (SOA) produced by atmospheric oxidation of primary emitted
precursors is a major contributor to fine particulate matter (PM2. 5) air pollution worldwide …

The carbonaceous particles represent a significant fraction in the particulate matter (PM) and

Secondary organic aerosols (SOAs) affect incoming solar radiation by interacting with light
at ultraviolet and visible wavelength ranges. However, the relationship between the …

Light-absorbing organic carbon (or brown carbon, BrC) has been recognized as a critical
driver in regional-to-global climate change on account of its significant contribution to light …

Existing studies on vertical profiling of black carbon (BC) and ozone (O 3) were mainly
conducted in the rural areas, leading to limited knowledge of their vertical distributions in the …
